EDMUND LUNK'ENHEIMER, OF CINCINNATI, OHIO, ASSIGNOR, BY MESNEASSIGNMENTS, TO THE LUNKENHEIMER BRASS MANUFACTURING COMPANY, OF SAMEPLACE.

OIL-CU P.

SPECIFICATION forming part of Letters Patent No. 418,578, dated December31 1889.

Application filed February 4, 1889- Serial No. 298,625. (No model.)

To all whom it may concern:

Be it known that I, EDMUND LUNKENHEIMER, a citizen of the United States,residing at Oincinnati, in the county of Hamilton and State of Ohio,haveinvented certain new and useful Improvements in Oil-Cups, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawings, forming part of this specification.

My invention is an improvement upon that shown and described in reissuedLetters Patcut No. 10,918, granted me March 15, 1887; and in its generalfeatures of construction my present cup is the same as that shown insaid patent.

In the accompanying drawings, Figure 1 is a sectional elevation of myimproved oil-cup. Fig. 2 is a top plan view of the cup. Fig. 3 is a topplan view with the valve-stem and binding-nut removed. Fig.eisaperspective view of the washer and spring. Fig. 5 is a sectionalelevation of a modified 'form of cup.

The same letters of reference are used to indicate identical parts inall the figures.

A represents the metal base of the cup, having the upwardly-extendingtube '13 communicating with the discharge-channel O in the base A, andprovided with the orifice D opening into the interior of the cup.

E is the glass cylinder forming the body of the cup, and F the metal capfitting thereonand having a central opening for the passage of the tubeB, and an opening G at one side through which the cup is filled withoil.

II is the valve-stem, pointed at its lower end and having a threadedportion a. engaging threads on the interior of the tube B, so that thevalve-stem mayby turning be adjusted up and down to regulate the feed ofthe oil through the channel O. The valve-stem is provided at its upperend with a polygonal thumb-nut I, by which it maybe turned. The

upper end of the tube Bis threaded exteriorly, and has one side cut awayor flattened, for a purpose to be presently explained. 1

J is a swinging scutcheon loosely swiveled on the tube B, so that it canbe moved sidewise on the cap F to cover and uncover the filling-holeG,while b is a pin or stop on the cap F to limit the movement of thescutcheon J. K is a fiat-sided 0r D-shaped washer fitted around the tubeB and resting on the scutcheon J, its flat side'fitting the flattenedportion of the tube B,'so that the Washer cannot be turned thereon.

Lis a binding-nut screwed on the upper end of the tube B and serving tobind the base'A, cylinder E, cap F, scutcheon J, and washer K together.The binding-nut thus regulates the friction against which the scutcheonJ must be moved in uncovering and covering the filling-hole G, and bymeans of the D-shaped washer interposed between said scutcheon and nutand fitting the flat side of the tube B, the movements of the scutcheonto and fro in uncovering and covering the hole G are prevented frombeing communicated to and turning the nut L, so that the latter will'always remain where set.

The parts of the cup thus far described are substantially the same asshown and described in my prior patent before referred to, andconstitute a very simple and eflicient oil-cup for most classes of work;but in the use of cups of this class for some purposes, especially intheir use on locomotives, it is found necessary, or at least verydesirable, to provide some additional means for positively holding thevalve-stem H from being loosened and turned, and the adjustmentiof thefeed thereby destroyed by the shaking and jarring of the cup. Differentmeans have been provided for this purpose, consisting in one case of apendent arm pivoted to the top of the valve-stem or an extensionthereof, and having its lower end or edge arranged to engage and be heldin different adjusted positions by notches in the outer edge of the capF. As another means of accomplishing the same object, a coiled springhas been placed around the valve-stem between the top of the binding-nutand the bottom of the thumb-nut'on the upper end of the valve-stem butboth of said devices have been objectionable, the first as being more orless clumsy and expensive and both proving inefficient where the cup wassubjected to severe shaking or jarring.

In the present case I have produced, for accomplishin g the abovedesired object, a device I, and under its simplest arrangement formingan integral upwardly-extending portion of the D-shaped washer K, as seenmore particularly in Fig. 4. This spring is made of sufiicient rigidityto bear against the nut I- sides, I do not wish to be limited to theexact shape of said nut and spring; nor do I wish to be limited to theparticular construction of the body of the cup. For instance,myinvention is equally applicable to a cup whose body is constructedentirely of metal, as shown in Fig. 5, the sides and base beingpreferably cast in one piece and the top cap screwed into the body, inwhich case the tube B, not being needed to bind the several parts of thebody of the cup together, may extend a short distance above and belowthe top cap F, thus afiording a bearing for the valve-stein H, scutcheonJ, washer K, and nut L. Again, while thesimplest and most desirablearrangement of the spring M is to form it of one piece of metal with thewasher K, yet it may be separate, and as a simple modification may forman upward extension of a secondary washer interposed between theD-washer K and binding-nut L.

Having thus fully described my invention, I claim- 1. In an oil-cup, thecombination,with the body of the cup having a central tube B projectingabove its top, said tube being screwthreaded exteriorly and having aflattened side, of the valve-stem H, extending through said tube andprovided with the thumb-nutI at itsupper end, the cap, the swingingscutcheon J, swiveled on the projecting portion of the central tube B,and arranged to be moved sidewise to uncover and cover a filling-hole inthe cap, a binding-nut L on the upper end of the tube B, and aflat-sided or D-shaped washer K, interposed between said scutcheon andbinding-nut and fitting the flattened side of the tube B, said washerbeing provided with the integral upwardly-extending spring M, engagingthe thumb-nut I, substantially as and for the purpose described.

2. In an oil-cup, the combination of the base A, glass cylinder 0, capF, having the filling-hole G, tube B, threaded at its upper end andhaving one side flattened or cutaway, valve-stem 11, extending throughsaid tube and provided at its upper end with the thumbnut I, swingingscutcheon J, swiveled on said tube and arranged to be moved sidewise tocover and uncover the filling-hole G, bindingnut L on the upper end ofthe tube B, D- shaped washer K, interposed between the scutcheon J andbinding-nut L, and having the integral upwardly-extending spring M,engaging the thumb-nut I, substantially as and for the purposedescribed.

EDMUND LUNKENHEIMER.
